I agree with the oil users. I see no reason to use grease.
Mechanical parts barely need any lubrication when they don't move relative =
to one another, except perhaps a tiny amount to prevent sticking on release=
. So when you're pedaling and your freehub pawls are transmitting torque, =
they don't care about lube.
Mechanical parts need only very light lubrication when they're moving but n=
ot carrying loads. When you're coasting, the only loads are the weight of =
the cassettes and a tiny bit of derailleur tension on the chain. Near zero =
load needs near zero lubrication.
Oil will give enough lubrication, and you won't have to worry about grease =
possibly restricting the pawl engagement.
